It is an undeniable fact that frequency inverters provide the most benefits of the many methods of controlling induction electric motors. However, in some cases the use of a frequency inverter can have a negative effect on the motor. One of the causes of damage to electric motors due to the inverter effect, happens when the power cable between these two devices is too long. But why?The output of the frequency inverter is characterized by a PWM signal (Figure 2). Considering this signal, we will observe...

With all Power Meters, Power Quality Analyzers, Energy Loggers or Power Loggers you can measure quite a number of Power parameters. In fact, the number of variables these instruments can measure, log and store is in many cases overwhelming. Imagine yourself setting up, downloading and analyzing a 32GB file with a logging of 500+ parameters over a month period…..So, wishing for “I want to log everything” is in most cases not the best idea, and certainly not the most efficient way. This leaves...

Power Quality loggers are often placed in the field for long periods, so most don’t have a display. Besides attracting attention and so increasing the chance of theft, a display is simply not needed as you don’t normally use a logger for troubleshooting. Successful analysis is therefore all about gathering data.Somehow, you need to communicate with the logger. You need to tell it what and how to measure, and then download the data. With no display, a logger’s communication links are critical,...

Grid connected photovoltaic systems are growing in importance as sustainable energy sources.The DC power of the solar panels is converted into an AC power by inverters. These are transformerless and, besides generating AC current, also inject a small DC Current. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause additional losses and reduce transformer lifetime. For measuring these DC components, we need a Power Quality Analyzer...

Large three-phase motors and the equipment they drive should consume power equally from each of the three mains phases. However, that often doesn’t happen. Unbalance and harmonics can cause instability, with motor vibration that reduces both efficiency and lifetime. Unbalance can also cause malfunctions in single-phase loads. All this can reduce your power quality, leading to punitive penalty charges from your utility.In this blog, we will describe balanced three-phase power systems – where each...

When you perform an energy or power quality survey you need to measure days or weeks of data, imagine the disappointment if when you return to the logger after that time you discover that you have failed to capture the correct measurements. The support teams at Fluke all too often get calls from users who don’t understand the measurements they have logged, usually they think the instrument is at fault. Usually though the problem is due to the user making a connection error, this can be due to incorrect...

More than 40% of industrial motors work at or below 40% of their load rating. That means poor power factor and inefficient operation. Efficiency of all motors can drop over their lifetime, which increases energy and maintenance costs and can even increase plant downtime. Monitoring drive efficiency catches the symptoms early.The four key power quality measures are:active (real, useful) power in KW,apparent power (complex, that you actually pay for) in kVA,reactive (imaginary, wasted) power in kvar,...

Harmonics can cause high neutral currents in three-phase systems — even ones that are balanced. They heat up cables, which can cause fires. Many installers now check their work using a multimeter, but multimeters can’t measure harmonics.Equipment installation needs a power quality analyzerResistive (linear) loads like heating elements and incandescent lights used to dominate electrical supply networks. The last 10 years has, however, seen many more non-linear loads. Examples are LED lights, variable-speed...

What is IEC 61000-4-30 standard?The IEC 61000-4-30 standard ensures that the measurement results from Power Quality analyzers and loggers of different makes and models match up; so measurement results are comparable without any doubts. This is extremely important, especially when there is a dispute about supply voltage quality between different parties going on. To comply with this standard, the instruments should measure and evaluate in exactly the same way. The standard covers PQ phenomena like...

The 4 mA to 20 mA current loop is a common method of transmitting sensor information in many industrial process monitoring applications—typically in systems monitoring pressure, temperature, pH, flow, or other physical factors. These systems employ a two-wire, 4 mA to 20 mA current loop, in which a single twisted-pair cable supplies power to a transmitter and also carries the output signal.The loop’s operation is straightforward: a sensor’s output voltage is first converted to a proportional...

Resistance is measured using analog or digital multimeters. These tools also measure current, voltage, and more for various applications. Why measure resistance? To determine the condition of a circuit or component. The higher the resistance, the lower the current flow, and vice versa.In general, the resistance of components used to control circuits (such as switches and relay contacts) starts out very low and increases over time due to factors such as wear and dirt. Loads such as motors and solenoids...

Circuits and equipment may be designed to operate at a fixed or variable frequency. They may perform abnormally if operated at a different frequency than specified.For example, an AC motor designed to operate at 60 Hz operates slower if the frequency is less than 60 Hz, or faster if frequency exceeds 60 Hz. For AC motors, any change in frequency causes a proportional change in motor speed. A five percent reduction in frequency yields a five percent reduction in motor speed.Looking for your first...
